abstract

  • In this paper, we report on design rules for optimizing the response of intensity sensors embedded in ring resonators (RR) as part of a frequency based self-referencing method. Time division multiplexing sensor networks require a time response analysis for properly addressing the self-reference sensors. The selected measurement and reference frequencies are multiples of the RR Free Spectral Range to improve signal to noise ratio and avoid RR coupling coefficient (K) tolerance influence on the measurements. A weighting function that models the trade-off between high sensitivity and fast response for defining the operation point in terms of K and ring losses is also given.
